(ci. 2li-521) 1 claim. 1

This invention lrelates'to window construction, and more particularlyhas reference to the type of window `construction that is particularlyadaptedrfor 'use in concrete Abuilding structures, although it can aswell be used in structures of other types.

An important object of the present invention is to provide a windowconstruction wherein a plurality of channels are utilized, with eachchannel accommodating double hung sashes, the upper and lower sashes ofeach channel adapted to be recessed entirely within the wall above andbelow the window frame.

lAnother important object is to provide a window construction of thetype stated wherein one set of sashes can be equipped with the usualglass panes, another set can be formed as screen sashes, and the thirdset can comprise reproof shutters of vermiculite or similar material.

Another important object is to provide a Window construction as statedwherein the upper and lower sashes of each channel have a cord andpulley connection with each other in such a way that the raising of theupper sash into the recess above the window will cause the lower sash tobe dropped into the recess below the window, so that both of said sasheswill clear the window aperture entirely if desired.

With the foregoing and other objects in vieW which will appear as thedescription proceeds, the invention consists of certain novel details ofconstruction and combinations of parts, hereinafter more fully describedand pointed out in the claim, it being understood that changes may bemade in the construction and arrangement of parts without departing fromthe spirit of the invention as claimed.

Referring to the drawings, y

Fig. '7Y is a section on line 'i-l of Fig. 6.

.Referring to the drawings in detail', I have v2 particularlydesignedthe window assembly .to be described hereinafter, so that it may beutilized in buildings'con'strcted allor in greatest part of `concrete orsimilar cernentitious "material. However, at this point it should benoted that as will be apparent hereinafter, the 'construction 'of theVwindow assemblyY does not preclude its "use in other types of buildingstructures.

In any event, in the illustrated "example a concrete floor 5 isprovided-and a concrete 'ceiling i6, 'while 'I designates a concretebuilding wall `formed with an aperture for a window, and set into theconcrete wall 'l at the sidesof saidaperture are the concrete posts 8.

Above the window aperture, I provide (Fig. 2) ain'inner top wall slab 9andan outer top wall slab I0 spaced apart to define a jpocketil 'inwhich the 'upper sashes of the window assembly are adapted to berecessed in a manner t`o be 'described hereinafter.

Below the window aperture I provide the inner bottom slab I2 and the`outer bottom slab I3 spaced apart to define the lower pocket vlli'receiving the bottom sashes. l

If necessary the pocket II can be 'extended upwardly above the ceiling 6as shown lat I5, and the pocket I4 can be extended below 'the oor 5 asat I6.v K,

Mounted against the concrete posts 8 'are parallel vchannels I1, I8,andv I9 `respectively (see Fig. 5) and these are oija length to extendupwardly 'along the side walls of the respective lupper and lowerpockets to the inner ends of said pockets. The channels I1, I8, i9 canbe securely mounted in place in any suitable 'manner, but I prefer thatthe channels 'be vformed with openings 20 `-adapted to receive screwsthat can extend into the concrete posts 8 int'o threaded engagement withnuts embedded in said posts.

The channel I1 is adapted to provide-aslideway for the upper and lowerwindow sa'shes, the channel I8 is adapted to provide a slidf'eway 'forthe upper and lower screen "sashes, andthe channel IS is adapted toprovide laslidewiay for the upper and lower Vflreproof shutters.

The construction of the window sashes. which will be the innermost pairof sashes in. most instances, will first be described, and the upper andlower window sashes are `generally-designated 2| and 22 and :are shownin partially open or recessed position in 1. yThe uppersash 2| istypical, and is provided with a metal frame including (Fig. 5) sideplates 23 ofjme'tal ma.- terialwelded at 24, to horizontal plates`25,;at the top and bottom of the sash. Horizontal this end, there aresecured to the opposite sides of the sashes the outwardly extendedchanneled guides 3i (see Fig. 5) which are mounted for sliding movementin the respective sash runs or -channels Il.

By reason of this construction it will be seen that slidable mountingsfor the window sashes are provided, with there nevertheless beingprovided at opposite sides of each sash openings defined between theopposite side Walls of each of the channeled guides 3i These openings orvertical passageways are for a purpose to be apparent immediatelyhereinafter, there being secured to the respective upper corners of theupper window sash 2i the sash cords 32 that are extended upwardly asbest seen in Fig. l, and are trained over pulleys 33 mounted cn bracketsextending outwardly from the upper ends of the respective channels l1 asbest seen in Fig. 4. Thereafter, the sash -cords 32 are extendeddownwardly within the channels il and are extended through thepassageways described immediately above V(see Fig. 5). The lower ends ofthe sash cords 32 are then connected to the upper corners of the bottomsash 22.

By reason of this construction, it will be readily seen that when theupper window sash 2| is raised by a, user, the lower window sash 22 willmove downwardly. Assuming that the upper sash 2| is raised to itsmaximum extent, in which it is recessed fully within the top pocket, thebottom sash 22 will be moved downwardly a corresponding extent, so thatit is fully recessedwithin the lower pocket. Thus the window aperture iscleared entirely of theV sashes. In this connection, it will beappreciated that the sashes are of substantially identical construction,and are of the` same weight, so that one counterbalances the otherduring the raising andY lowering thereof.

Referring to Fig. '7, to the outer surface of the horizontal lower rail2S is secured a plate 35 that extends downwardly over the joint betweenthe top and bottom sashes when said sashes are in closed position asillustrated in Fig. 7, so as to provide a drip strip or joint coveringmeans to preventleakage through the sashes to the interior of thebuilding structure.

I believe that various means can be devised for locking the windows inclosed position and open position. However, I prefer that a means suchas shown in Fig. 6 be used for this purpose. In this gure there isillustrated a means for locking the windows in closed position wherein aswinging latch 36 has a beveled hook 3l at its lower end adapted toengage in registering openof swinging said latch to open or unlatchingposition when the hook 31 is out of engagement with the bottom sash 22.For this purpose, the shaft di extends out of the sleeve 40 as best seenin Fig. 7, and is extended laterally to provide an operating handle 32accessible from the interior of the building structure. When the windowsashes are moved to closed position, the cam portion or beveled surfaceof the hook 31 will be cammed outwardly so las to permit the latch toenter the registering openings 38 and 39 after which the latch 36 willautomatically move to a position in which the hook 31 will engage thebottom sash. A stop 43 is provided limiting movement of the latch in onedirection, and for the purpose of automatically engaging the latch withthe bottom sash, I provide the spring 43* secured to the latch and tothe bottom rail of the upper sash respectively.

I also provide a means for locking the windows in any selected openposition, and to this end there is provided in the top rail of thebottom sash a sliding bolt arrangement wherein a sleeve 45 extendsthrough said top rail of the bottom sash and has rotatably mountedtherein the shaft i3 of non-circular cross section, there being securedto the projecting portion of the shaft 35 the operating handle il forrotating said shaft.

. Secured rigidly to the inner end of the shaft 43 ings 38 and 39 of thetop and bottom sashes re- Vwithin said sleeve the shaft il! ofnon-circular cross-sectional conguration that is engaged with the upperend of the pivoted latch for the purpose for rotation thereby isV thedisc 38V and pivotally secured to the disc at diametrically` oppositepoints are the retractable bolts 49 that extend through openings in theopposite sides of the bottom sash so as to engage in any of a series ofopenings spaced vertically of the channels il thus to permit the vsashesto be locked in a selected openposition by adjustmentvof the bolts i3 tothe dotted line position illustrated in Fig. 6.

Referring now to the construction which I prefer to utilize for themiddle set of sashes comprising the screen sashes, reference Ashould behad to Figs. 2 land 3 .in which it is seen that each screen sash isprovided With a frame which is formed from channel members 5i) in whichare mounted wood fillers El. Screen mesh material 52 has its marginalportions engaged under retaining strips 53 formed with suitable openingsthrough which screws extend for the purpose of securing the marginalportions of the screen mesh material between the strips 53 and the woodfil-1ers 5l. TheseY screen sashes formed as described are connected by acord and pulley arrangement exactly `as in the case of the windowsashes, and the screen sashes slide in the middle channels I3. Thus,elevation of one screen sash to its maximum extent causes the otherscreen Sash to drop into the bottom pocket to its maximum extent so asto clear the window aperture entirely of the screen sashes wheneverdesired. This would be desirable in the wintertime perhaps, or on anyother occasion when screen sashes are not necessary.

Referring now to othe outer channels i 3,' these accommodate slidablymounted iireproof shut ters the construction of which is best shown inFigs. 2 and 3, each fireproof sash comprising a frame composed ofchannel members 54 einbracm ing the marginal portions of a vermiculiteshut- Y ter member 55 reinforced by wire mesh material 56.. Ordinarily,thereproof shutters can be recessed entirely within the upper and lowerpoehets, but if a fire occurs in a nearby structure, the shutters can beswiftly moved to closedV position, and in said position will hold backas much heat as the concrete Wall 1 itself. This is desirable because awindow is a vulnerable point in a concrete building, when a combustiblestructure is burning closely adjacent thereto. By provision of thefireproof shutters, the concrete structure in which it is preferred thewindow assembly be used is made wholly iireproof so far as ring of saidstructure from an adjacent burning structure is concerned.

Referringr again to Figs. 2 and 3, immediately A above and below thewindow aperture I provide the spacers extending transversely across saidaperture and disposed between and spacing apart the sash runs il, I8 andI9. These spacer members are each comprised of (see Fig. 3) opposed topand bottom channels 51 and 58 embracing the upper and lower longitudinaledges of a concrete bar S9 reinforced by wire mesh 5S.

The window stiles and rails may be constructed in several ways, but Iprefer to use stock channels about {'-5 x 2 inches for stiles and topand bottom rails, and le X 11/2 inches for meeting rails with the openside inside to be covered by a steel plate, spot-welded or ibrazed orscrewed on where it is necessary to remove plates for repairs.

Further, I believe it is also desirable to mention that the screen sashcan be made similarly to the window sash and i-ireproof shutters, with awooden core in the hollow space extending around the sash frame, towhich core the screen may be tacked. A face plate ci the frame can thenbe screwed on, and this plate, whenever necessary, can be removed forthe purpose of repairing screens.

What is claimed is:

In a window assembly for supporting upper and lower sashes in a Windowopening having spaced vertical side walls, vertically spaced channelmembers secured to opposite vertical side Walls of the window opening,said channel members opening into the vwindow opening and definingWithin and between them vertically spaced sash runways, a pair of spacedlaterally inclined arms carried by each channel member adjacent theupper end thereof, said arms extending into the window opening, a pulleymounted in each pair of arms for rotation about a horizontal axis whichlies parallel to the walls of the Window opening to cause diametricallyopposed portions of the periphery of said pulley to lie midway betweenadjacent runways, sashes mounted in adjacent runways to move verticallyin the window opening and cables trained over the pulleys and connectedto the sashes to cause the sashes to move in unison and in oppositedirections in the runways.
